PLANTER ATTACHMENT;

Application Vfiled August 5, 192,6'.-v Serial No.f1r27,f23.I f

This .invention yrelates to means ytor atcan be attained by theorganization and.

details of construction of the preferred embodiment hereinafterdescribed and in which the invention deined by the claims resides.

Referring' to the drawings- Fig. 1 is a plan view showing a plantercoupled to the rear end of a tractor in a manner embodying theinvention; and

Fig. 2 is a similar side view.

As here disclosed, the structure illustrat ing the invention comprisesan arched or U-shaped draft bar 1 the arms of which are hinged onhorizontal trunnions 11 on the inner sides of an arched rear axlestructure 12 of a tractor supportedV on traction wheels 18. The draftlbar 10 may be part 'of the regular tractor equipment. To this draft bar,and forming a unitary auxiliary carrying 'frame structure in combinationtherewith, are fixed a transverse beam 14 on the arch or bight of thebar 10 and a parallel bar 15 on the` forward ends of the arms of thebar. The bar lris preferably angle iron having a wide upstanding web 16which is braced on beam 14 by diagonal bars 15. The carryingV frame alsoconsists of a long central longitudinal main bar 17 fixed at its frontend to the `bar 15 and supporting a bearing bracket 18 on its rear end.This bracket comprises'a vertical bearing sleeve 19 secured to theupturned rear end 2O of the bar 17 as by two straps or collars 21. Thesleeve 19 has journaled in it the vertical portion 22 of a crankedstandard 28 on the lower end of which is journaled the ,ca-ster wheel24. The bracket 18 has fixed to it a rack piece 25 having a rearwardly`link 29 connects the lever 27 with a collar` 30 heldbetween stop collars31 on the upper end pf standard 2Q. bet-,Ween the lever and bracket andserves to assist the action of thelever when` swung down tolift Vtheauxiliary frame. Incorf poratcd in thev auxiliary 'frame structure andcarried by thel parts above described isthe frame and planting units ofa standard corn or cotton planter generally designated 33. This `planterhas the usualy axle, trac tion wheels, yand plantery units driven ,fromthe axle. The usual furrow openers 34, spouts l and covers 36 are shownin Fig. Qlbut other well known planter parts are omitted as unnecessaryto understanding 1of the present invention. The front of the planterframe, comprising cross bars 37 and 38, extends over the beam 14 andbraces 15"L but the main longitudinal bar 17 preferably passes over theplanter frame and is secured to its rear cross bar 39 by a. suitableclamp at 40. Braces 41 connect the rear end of bar 17 with cross bar 39.A clamp 42 secures the` front planter cross bar 38 to bar 17.

In the practice of the invention, the ordi-V nary horse draft gear ismoved from the planter and the auxiliary frame structure is securedthereto and this in turn secured to the arched draft bar 10 of thetractor. The planter is thus connected to the tractor so as to bemovable with respect thereto on the pivots 11 in a vertical directiononly. This permits the planter attachment as a whole to conform touneven surfaces and to beraised and lowered on the caster wheel 24through manipulation of lever 27 which is so shaped as to be alwayswithin reach of the operator on the rear of the tractorL As the planteris supported and driven by its own wheels when inlowered position itfollows that raising the planter also stops its operation. lVhen soraised the attaclr Vment is supported on the caster wheel and shortturns can be made by the tractor without interference and in much lessspace than required with the flexibly hitched trailing attachments ofthe prior art- W'hat is claimed as new is:

1. The combination with a vehicle having` A spring extends n cludinglaterally spaced arms pivoted to the vehicle on a horizontal axis, amultiple row planter including supporting Wheels carried by the trameand located in advance of said caster Wheel and Within the space spannedby the traction Wheels, and means for shitting the caster Wheel tobodilyfmove the planter supporting Wheels to and from the ground.

2. The combination comprising a vehicle having rear traction Wheels, ahorizontally extending arched bar between the Wheels with its armspiyoted to the vehicle for free vertical swing, an auxiliary traineextending rearwardly troni said arched bar and rigidly secured thereto,a caster Wheel supporting the rear of the auxiliary frame and shi'ftablevertically with respect thereto, a two-row planter secured to theauxiliary trarne including supporting Wheels loc-ated in the plane otthe traction Wheels, carried by the auxiliary frame, and means forshifting the caster Wheel to bodily raise and lower the planter.

3. A structure for attaching planters of standard types to tractorscomprising a main supporting bar adapted to extend in a fore and attdirection With respect to a planter'. trame and be secured thereto onthe longitudinal median line thereof, a vertically shitting the casterWheel to bodily raise and lower the bar and planter.

4l. A structure for attaching planters of standard types to tractorscomprising a main supporting bar adapted to extend in a fore and attdirection with respect to a planter frame and be secured thereto on itslongitudinal median line at points intermediate the ends of the bar, avertically shittable caster Wheel supporting the rear end or said bar, atrame fixed to the forward portion ot said bar adapted to extend betweenthe rear wheels or' a tractor' including laterally spaced arms havingmeans for horizontal pivotal connection to a tractor, and means forshitting the caster Wheel including a lever having a hand piece movablein an arc approaching the front end of said main supporting bar.

In testimony whereof We atlix our signatures.
